Charging issues on Samsung Chromebook Pro (Caroline) and Ubuntu

I installed Ubuntu on my Chromebook Pro, and I’m getting a weird charging behavior.

If I plug in the USB-C charger the laptop will charge slowly, ~7 hour to full charge. If I suspend with the cable plugged in, It will charge fast ~1hour to full charge.

If I unplug the cable and plug in again I will be back to slow charge ~7hrs to full. Again, suspending and coming back will fix this.

Does anyone have an idea of what can be happening or what changes after suspending?

Just noticed this also happens with my pixelbook running Linux Mint. Is anyone else experiencing this?
